wspr not working

Hi
Can any one help me with the following problem.
For the last three months I have been using wspr with no
problems at all.However for the last week the data base has shown no received reports on my transmissions and also I do not receive details of other transmission even when signals are shown on the waterfall display.
I have deleted wspr from the computer and downloaded the latest
version and it is still not working.
I know the transceiver is working and putting out power.WSJT and all other digital modes are working normally.The only clue is that
once in trying to get wspr to work I got an error message saying
" unable to access data base"

For issues with this site, email the WSPRNET Admin Team or post to the site forum. Downloads and more information about WSPR program and the MEPT_JT mode, as well as other modes by Joe Taylor (K1JT), can be found at the WSJT Home Page.
